Quick Answers

So, is Core i7-3770T better than Xeon E3-1240?

Not really, because they are built for different jobs. Xeon E3-1240 makes more sense for workstation-style multi-core throughput, while Core i7-3770T is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-3770T is the better pick. According to our tests, it delivers 5.2% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-3770T is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-3770T is still the faster CPU overall, but Xeon E3-1240 is easier to justify if budget matters more than peak performance. Core i7-3770T comes in 1.8% more expensive on MSRP at $278 MSRP versus $273 MSRP, and it still gives you a 5.2% average FPS lead across 50 shared CPU game tests in our data. Xeon E3-1240 is also 1.0% better value on MSRP (19.6 vs 19.4 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

Which one is more future-proof for 2026 and beyond?

Core i7-3770T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
